Like the title says, I keep getting the error You need to use a Theme.AppCompat theme (or descendant) with this even though I am using Theme.AppCompat.
First, Here is the class that is getting the error (NOTE: I marked the line where the error is occurring with a comment):
public class CustomSimpleCursorAdapter extends SimpleCursorAdapter {
private Context context;
private Cursor cursor;
private MainActivity mainActivity;
public CustomSimpleCursorAdapter(Context context, int layout, Cursor cursor, String[] from, int[] to, int flags, MainActivity mainActivity) {
super(context, layout, cursor, from, to, flags);
this.context = context;
this.cursor = cursor;
this.mainActivity = mainActivity;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent){
// Grab each row as it is pulled from the db.
DatabaseHelper dbHelper = new DatabaseHelper(context);
View row = super.getView(position, convertView, parent);
cursor.moveToPosition(position);
final Integer id = cursor.getInt(cursor.getColumnIndex("_id"));
final String personID = cursor.getString(cursor.getColumnIndex("personid"));
// Set alternating rows to different colors.
if(position % 2 == 0){
row.setBackgroundColor(Color.parseColor(Constants.WHITE));
} else {
row.setBackgroundColor(Color.parseColor(Constants.LIGHTGREY));
}
// Make the delete button clickable.
Button deletePersonButton = (Button)row.findViewById(R.id.remove_person);
deletePersonButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
AlertDialog.Builder deleteDialogBuilder = new AlertDialog.Builder(context);
deleteDialogBuilder.setTitle("Delete Person " + personID + "?");
deleteDialogBuilder.setMessage("This process is IRREVERSABLE!");
deleteDialogBuilder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
DatabaseHelper databaseHelper = new DatabaseHelper(context);
databaseHelper.deletePerson(personID);
mainActivity.dataChanged();
Toast.makeText(context, "Person " + personID + " (ID: " + Integer.toString(id) + ") Deleted", Toast.LENGTH_LONG).show();
}
});
deleteDialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
AlertDialog deleteDialog = deleteDialogBuilder.create();
deleteDialog.setIcon(R.drawable.warning);
deleteDialog.show(); // This is where I get the error
}
});
return row;
}
}
Here is where I call CustomSimpleCursorAdapter:
public class Home extends Fragment{
private MainActivity mainActivity;
private View rootView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
rootView = inflater.inflate(R.layout.home, container, false);
mainActivity = (MainActivity)getActivity();
return rootView;
}
@Override
public void onViewCreated(View rootView, Bundle savedInstanceState) {
super.onViewCreated(rootView, savedInstanceState);
drawThePersonView();
}
public void drawThePersonView(){
Context context = mainActivity.getApplicationContext();
DatabaseHelper myDBHelper = new DatabaseHelper(context);
Cursor personCursor = myDBHelper.getUndeletedCasualtiesCursor();
String[] fromColumns = {"_id","personID","location","status"};
int[] toViews = {R.id.person_number_textview, R.id.person_personID_textview, R.id.person_location_textview, R.id.person_status_textview};
CustomSimpleCursorAdapter mySimpleCursorAdapter = new CustomSimpleCursorAdapter(context, R.layout.person_layout, personCursor, fromColumns, toViews, 0, mainActivity);
ListView myListView = (ListView) rootView.findViewById(R.id.person_row);
// Draw the list
myListView.setAdapter(mySimpleCursorAdapter);
myDBHelper.close();
}
}
And here is my AndroidManifest.xml file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.domain">

<activity
android:name=".AddItem"
android:label="@string/title_activity_add_item"
android:theme="@style/AppTheme.NoActionBar" />
</application>
</manifest>
In the above manifest I posted, there is no reference to Theme.AppCompat, but I did make that change before I posted here. I changed one at a time, then I changed them all from what they were to Theme.AppCompat and I still received the error every single time even though I am using Theme.AppCompat.
This is the logcat of the error:

Any suggestions?
Thanks!
